【 摘 要 】

A nonlinear model for predicting the resonant oscillations in a harbour due to typhoon is developed and its validity is evaluated through the comparisons with filed measurements obtained in Yui Fishery Harbour facing Suruga Bay in Japan. The numerical model is based on a time domain solution of Boussinesq equations proposed by Nwogu(1993) with an additional Forchheimer resistance term in the momentum equation to take account of the reflection characteristics of permeable seawalls in the field. It is shown that the numerical model predicts well the lowfrequency oscillations inside the harbour exited by incident wave groups.
